Abstract
New data on the state of Cr3+ ion impurities in a single crystal of YGa3(BO3)4 were obtained from analysis of the electron paramagnetic resonance spectra. Crystal structure, lattice parameters, and atomic position of this crystal were studied by X-ray powder diffraction method. The Cr3+ ions are found to substitute for the trivalent gallium ions. The spectra of Cr3+ ions located at three magnetically nonequivalent sites that rotated through 120°C are registered. The obtained parameters of spin Hamiltonian of the Cr3+ ions in the YGa3(BO3)4 single crystal were analyzed. Crystal structure, lattice parameters, and atomic position of this crystal are studied by X-ray powder diffraction method. [ABSTRACT FROM AUTHOR]
